Public Function GetSignedElement( _
   ByVal signatureItem As DicomElement, _
   ByVal index As Integer _
) As DicomElement

Visual Basic (Usage)	Copy Code
Dim instance As DicomDataSet Dim signatureItem As DicomElement Dim index As Integer Dim value As DicomElement   value = instance.GetSignedElement(signatureItem, index)

public DicomElement GetSignedElement( 
   DicomElement signatureItem,
   int index
)

public:
DicomElement^ GetSignedElement( 
   DicomElement^ signatureItem,
   int index
) 

Parameters

signatureItem

The Digital Signatures Sequence Item that corresponds to the Digital Signature. This cannot be null.

index

The zero-based index of the required signed Data Element. This should be a number from 0 to GetSignedElementsCount(signatureItem) - 1.

Return Value

The GetSignedElementsCount method returns the number of signed Data Elements as specified by the Data Elements Signed (0400,0020). The Leadtools.Dicom.DicomDataSet.GetSignedElement method searches the level at which the MAC Parameters Sequence appears for the Data Element with the tag determined by the passed index and returns the Data Element if it does exist; if it does not exist, the method returns a null reference (Nothing in Visual Basic).

Note: In addition to the Data Elements specified by the Data Elements Signed (0400,0020), certain Data Elements under the Digital Signatures Sequence Item are always covered by the Digital Signature.

The following methods can also be used to get information about the Digital Signature:

Leadtools.Dicom.DicomDataSet.GetSignatureUID

Leadtools.Dicom.DicomDataSet.GetSignatureDateTime

Leadtools.Dicom.DicomDataSet.GetMacTransferSyntax

GetMacAlgorithm
